Ooooo!!!...this might definitely catch on...really!! So when are we getting a rocksprinter out to grade the walkin to oorlogskloof (some real nice riverbeds there... ), and they can add a grade to the difficulty if you do it with a pack full of climbing gear!!!

Derek: I posted the link in my post above because at the time the link you had posted was incorrect (an extra t in http and another error). I have no strong opinions on your video, but I did want to watch it, and got to the video via your website.

I thought I was doing everyone a favour in posting the correct link. I was not rude, please pay me the same courtesy.

The signature explains how I came to have the nickname some 15 years ago.

On saturday night there was a massive group of trail runners who did Devils Peak, Maclears Beacon, and Lions Head consecutively, in a wet gale with buggerall visibility. When I left that area in the early hours to move our rescue base to another location there were still okes coming down Platteklip and heading up Lions Head. I'm pretty sure I saw Ross Suter jogging past at one stage actually (well it was a smiling fit-looking hairy dude)

Those trail running guys n gals could learn a thing or two from the rock sprinting crowd

Howzit all you guys n girls who have replied to the rock sprinting site ...

Thanks so much for all your comments, it really made my day to see all the interest the site (and now the video, recently posted) have generated. I never knew mountain climbers had such a cool sense of humour (except for my dad, Neville Davey, who was an avid climber and possessed a wicked wit).

To Mr Not, apologies if my reply appeared rude, but it seems to have been deleted from this posting anyway; all I was trying to say was, let's all be positive and creative and keep it light, 'cos life is a short ride and what's the point of being negative and/or miff?

The more feedback I get about rock sprinting, the more I am realising that this is not a sport I invented at all, I was just perhaps the first to give it a name and identity. There seems to be loads of fellow crazies who just love leaping from boulder to boulder and sprinting along rocky craggs, so my appeal now is: if you are one of these mullets, please film your own videos and send them in to the rock sprinting site - we want to see them, man!

hey Derek, since you actually seem to be serious about this (I thought it must be a joke), I have a few questions for you.

How is this 'sport' defined? People have been boulder hopping/kloofing for ages. Ever been Kloofing in the Magaliesburg, jumped off 'Help Help'?

IMO for something to be a new sport it needs to have some sort of definition. If what you guys were doing was in anyway acrobatic or hardcore, perhaps 'Natural Parkour' could be termed.From watching the video, between the tears of course, I fail to see the point of what you guys are doing. We trail run here in the Cape and our average day out running far exceeds what I saw in the videos. It's par for the course basically.

Now there are some seriously hardcore dudes who frequent this site, guys who solo climb cliffs and trek up insane peaks, only to fly off on a speedwing. How do you gauge a progression in this sport of yours? Where is the limit, what defines the difficulty?

I'd also think that from seeing the video, you guys are not protecting yourselves properly. A cycling helmet hardly protects one. I'd think you'd need shin and knee pads, elbow protection, full fingered gloves, as well as wrist protection, and then some better form of head protection (depending on how much there is to actually protect;)

Have you guys thought of introducing some form of 'RAD factor' to the sport? Check out this clip to see what I mean ( http://www.youtube.com/watch?v=eUJ-7_v9 ... 9CE72D3E7D ). Perhaps you guys could even join forces and create the new uber-geil passtime, complete with t-shirts, branded Energade bottles and action figures.

Rang a few bells about what the yanks used to call "Talus Running".There was a whole chapter devoted to it in a book called Rock Climbing? in the early eighties? Did a quick google on talus running and heres the first entry.http://www.spadout.com/a/running-talus-revisited/I seem to remember seeing pictures of John Bachar doing it too (of course he didnt use helmets, or pads come to that) but he was a bit different.Anyway Derek, sounds cool. Good luck and enjoy it.

rock sprinting fans, please not there is a great story about Doug Robinson running the talus,which is under 'news' (proving that rock sprinting has been around in different forms for some time now, the article is from the 70s)and there is also a great story about running from bushpigs, under the new post 'stories'

I keep thinking Derek is surely taking us all for a ride. This can't be happening. Every time a new post comes up I check to see if Derek uploaded a photo of him bent and with his butt facing the camera.I sincerely hope the light at the end of the tunnel comes soon.

On a serious note: You are welcome to join us when we go kloofing in the Magaliesberg. I'm not sure where you're based, but the geology and flora on the video looked like it's Magalies.If you got a kick out of the 'stunts' on your video, you'll be blown away the Kloofs.

Couple of years ago, before the climbing bug bit me, when I felt depressed, and the whole world wanted to crush me I went to Kaapsehoop close to Nelspruit on weekends. There I did the same thing until the loonyness wore off. Great running and jumping around right on the escarpment!..and a very creative way to potentially go home with multiple fractures to brag about.
